bhp guess
what sort of bhp do you thing i should be hitting, ive got a uk 95. heres the list.
custom airfillter set up. 480 sti injectors. full magnex decat + back box. td05 turbo. z4 ecu. lightend flywheel. light pullies, alternator/ cranck pullie. welbo 255 fuel pump. this is the engine side anyways. what do you think i should get...:wonder: |
for got to add' notification by e-mall':norty:
|
i would say about 250 ish at a push. Would go to an aftermarket ecu and you would get over 300 prob about 320 ish with that spec
|
I'd guess at high 200's...... ish!

Like i said, high 200's... ie, 28? or 29?.... lucky to get 300 i'd say... but maybe....

Bigger injectors on there own will not give an increase in power whilst running a standard ecu. Infact it will probably even lose you power and will certainly hurt economy. |
Also a lightened flywheel will not give you an extra 30bhp. It will reduce the power lost through transmission//drivetrain but I would be surprised if it was the equivalent of 30bhp

With a power fc and the mods you have I think you could get 320 ish quite easily. The top mount is good I believe for about 350 but your injectors would be maxed out by then.

ya ok matty, as i put. this is the claim from the company im getting it from. it'll cost 200 quid. i just put the claims from the comanys that sell them.:thumb:

if you fit larger injectors on the standard map it will run less power as it will just run way to rich.
biggest problem will be that intercooler and the map.. the RA intercooler is the same as the standard one if I remember correct.. Simon |

im putting this flywheel in next month when i change the clutch.. |

the ra cooler is very slightly larger to the rear, when compaired to the standard uk cooler. the car i have is a/was a standard uk95. every thing ive done. had improved the car. the injectors are better, not to much bigger from the 380cc. the ecu i had before was a 7d uk, the ecu z4 is better for the 440/480 sti phase two injectors. the engine is running cooler now too.the only thing i dont like is the speed limitor.

The Z4 is a 380cc injector map.. it will be running rich..
The phase 2 yellow injectors are 440cc btw. Water temp cooler or EGT? Simon |

has the fuel pressure been tweaked down to compensate?

no the fuel pressure in the rails will be regulated to standard pressure if you have the standard fuel pressure regulator on there. 440 injectors is not enough to lower the fuel pressure by using lots of fuel out of the rails etc..

im also thinking of getting a nocklink fitted. :norty:

are you actually going to get this crate tested? if not why are we all guessing? |
if it is running very rich you will be washing the bores of oil..

Not only are the injectors making the car rich when open loop, but there is a possibility of the 255 pump overpowering the regulator and making the car run richer! you may well be getting similar mileage due to the previous chip running the car rich also! Also if most miles are done closed loop then the ECU should be able to adjust fueling to get decent AFRs irrespective of larger injectors.
Personally I'd refit the 380's untill you get the funds for a remap. I think a decent remap should get you low 300's |
What Jay said except open and closed loop is around the other way..
sorry sound picky now.. |
